ATTACHMENT FOR GRAIN-BINDERS.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed January 2, 1915. Serial No. 162.

To all whom it may concern:

Be it known that I, EARL E. SAYLoR, a citizen of the United States, residingat Campbell, in the county of Franklin and State of Nebraska, have invented certain new and useful Improvements in Attachments for Grain-Binders, of which the following is a specification.

This invention relates to grain binders, and my object is to produce an attachment for guarding against contact between the knotter and disk of the binding mechanism and the loose or unbound straw upon the underlying deck.

A further object is to produce an attachment which has the additional function of holding back the advancing loose or unbound straw to effect a light packing or condensing of the same before the needle rises. The attachment is caused by the accumulating straw to swing upward out of the path of such straw .to a position where it underlies the opening in the breast plate through which slightly projects the knotting mechanism disk in binders equipped with what is known as the Appleby binder head, said attachment when raised preventing straw from entering the opening in the breast plate and catching and subsequently discharging below the breast plate pieces of waste twine which drop through said open- To these ends the invention consists in certain novel and peculiar features of construction as hereinafter described and claimed: and in order that it may be fully understood reference is to be had to the accompanying drawing, in which Figure 1, is a side view of a part of a grain binder equipped with an attachment embodying my invention. Fig. 2, is an inverted plan view of the construction shown in Fig. 1, with the deck of the binder omitted. Fig. 3, is a detailed perspective view of the attachment.

In the said drawing, 1 indicates the deck, 2 the breast plate-above the deck and provided with a longitudinal slot 3, and depending walls 4 at opposite sides of said slot. The plate is also provided with an opening 5, and with brackets 6 (one only appearing) forming journals for certain mechanism which is omitted as it constitutes a part of the Appleby binder head.

The opening 5 is provided not only to accommodate part of the Appleby binder head mechanism but also to permit the waste of twine incidental to the tying of the bundles, to drop through said opening out of the way. The opening thus provided is objectionable in that with binders lacking my attachment, except those equipped with what is known as the McCormick head, the straw upon the deck comes into contact with the disk and even works up through the said opening to a position where the needle draws the twine and frequently causes a slip or unbound bundle. My attachment is designed to overcome the last named difficulty without interfering with the escape of the waste twine, and incidentally to effect a preliminary packing or condensing of the loose or unbound straw upon the deck.

Indicated in dotted lines in raised or operative position is the needle 7 of the binder, the same working through the slot 3 and between walls 4 and over the opening 5 of.

the plate 2, in the customary manner.

My attachment consists of a swinging plate 8 suspended from plate 2 so that when swung upward its full distance it shall underlie opening 5, and thus guard against straw upon the deck working up through the opening 5. The attachment is also of such length that it may rest upon the deck and thereby intercept all of the straw that may be moved downward on the deck, in the direction indicated by the arrow, Fig. 1.

To prevent the body portion of the swinging plate from striking the breast plate, when the former is swung upward by the straw, andto avoid closing the opening 5 to the escape therethrough of the waste pieces of twine, the spacing walls are provided,

the same being formed preferably as a part of plate 8. In the drawing said walls are numbered 9 and project from the side margins of the plate, the upper edges of the walls being contoured to correspond to the curvature of plate 2 so as to closely engage the same when the guard plate is elevated.

The upper end of the guard plate is formed with an opening 10 through which the walls 4 extend, and through which a part of the needle passes in the movement of the same to and from operative position. The upper end of the plate at opposite sides of opening 10 therein, is formed with loops 11 receiving pivot pins 12 disposed at opposite sides of the walls 4, said pins being provided at their outer ends with heads 13,

riveted or otherwise suitably secured to 'plate 2.

V downward on the deck will accumulate opening 10.

against the guard plate and gradually raise the same from the position'shown in full lines to the position shown by dotted lines. Immediately this operation of the plate is accomplished, the needle swings to operative position and the bundle is tied, the

severed piece of twine dropping through opening 5 onto the plate 8 and the bundle being kicked onto the bundle carrier in the customary manner. The removal of the bundle permits the plate to drop down to its original position and thus perform the straw checking function preliminary to the completion of the next bundle.

In the actual operation of making bundles, the lip l-l hereinbefore referred to performs no function, but with the parts proportioned as 1 have them inactual practice, I have found such lip essential when demon strating Without any straw in the machine to hold the swinging plate raised, to avoid any possibility of the needle catching on the attachment or plate at the lower end of The convex face of the lip presents a surface which the needle cannot catch upon. 7

From the above description it will be apparent that I have produced an attachment for grain binders, embodying the features of advantage enumerated as desirable, and while I have illustrated and described the preferred embodiment of the invention,

-it is to be understood that I reserve the right to make such changes in the form, proportion,detail construction and arrangement of the parts as properly fall within the spirit and scope of the appended claims.

'I claim: V

1. The combination in a grain binder, of

a deck a breast plate oppositethe same provided with a slot and an opening at one end of the slot, of a p-latepivotally attached to the breastplate and adapted to extend downwardly therefrom across the space between the breast plate and the deck and to be swung upwardly and forwardly until it covers the said opening in the breast plate,

and means for arresting the upward swinging movement of said pivoted plate to prevent it from closing the said opening to the passage down through the same of an object from a point above the breast plate.

' 2. The combination in a grain binder provided with a deck, abreast plate above the deck provided with a slot and an opening at one end of the slot, and'a guardplate pivotally attached to the breast plate atthe rear end of the said opening and provided with upwardly projecting "side walls; said side walls being adapted to strike against the under sideof the breast plate at opposite sides of'said opening to cover said opening from below without interfering with the passage through said opening of an object from a point above the breast plate.

3. The combination in a grain binder of a deck, a breast plate above the deck provided with a slot, an opening forward'of the slot and walls depending at opposite sides of the slot, and a 'guardplate pivotally attached 'to the breast plate and adapt-' ed to swing from a position underlying said opening to a position rearward of said opening and providedwith upwardly projecting side walls to arrest the upward movement of said pivoted plate by contact with the breast plate and with a slot to receive the walls depending from the breast plate.
